THOMAS FREDRICK BARSBY, OF SEATTLE, WASHINGTON, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO UNIVERSITY GARAGE COMPANY, 0F SEATTLE, WASHINGTON, A CORPO- RATION.

Specification of Letters Patent. Patented Aug. 2?, 1918.

Application led .Tune 6, 1916. Serial No. 102,103.

To all whom 'it may concern Be ity known that I, THoMis FnnDRrcK Bansr, citizen ot' the United States, residing at Seattle, in the county of King and State of Washington, have invented a certain new and useful improvement in Motor- Vehicles, of which the following is a speciiication.

My invention relates to improvements in motor vehicles, and the object of my invention to provide operative mechanism that port-ions of one ot two transversely disposed tubes 14s which are rigidly united to form a shaft housing, within each ot which tubes 1l is disposed a shatt, as the shaft 15, which connected at one ot its ends with a dif- Jcrential gearing that is associated with the driving shaft 1G ot' the automobile, while its other end portion extends through the respective one of the bosses 13 to project outwardly through its disk 12 and mounted securely on such outwardly7 projecting end may be added to the chassis oi a passenger automobile oi" a common type and be associated with the driving shaft thereof, whereby such automobile may be converted into a freight carrying motor truck that will travel at a much slower speed in response to a given number ot revolutions per minute ot its driving shaft.

I accomplish this object by devices illustrated in the accompanying' drawings wherein Figure 1 is a plan View ot' a structure embodying my invention; Fig. 2 is a fragmentary view ot' the same on a larger scale 1n vertical section on broken line cc, :a of Fig. 1; Fig. is a view of the same in horizontal section on broken line jz/, y of Fig. 2; and Fig. i is a sectional view ot parts ot' the same on broken line .2, .a of Fig. 3.

Referring to the drawings, throughout which like reference numerals designate like parts, and 6 are side rails and 7 is an end rail of a trame that is adapted to loe spliced to the rear end portion of the side rails ot the chassis of an automobile from which the rear wheels and bearings thereof have been removed.

Secured in a well known manner to the outer side ot' each of the side rails 5 and 6 is a carriage spring, as springs 9 and 10 respectively, the central portion of each ot which springs 9 and 10 is clamped in a well known manner to an adjacent one of hubs 11 each of which is rigidly secured to an adjacent part of one ot the opposite end portions ot' an axle S which is transversely disposed beneath the side rails 5 and 6, as shown in Fig. 1.

On the outer end ot each of the hubs 11 is concentrically disposed a disk i12 that is integral therewith.

Each of the disks 12 is provided with a boss 13 within which is concentrically disposed to extend therethrough one of the end portion ot each ot' said shafts 15 is a pinion 17, as shown more clearly in Figs. 3 and 4.

Rotatably mounted on roller bearings 18 on each of the opposite end portions of the axle 8 adjacent to the respective one of the disks 12 is the hub 19 of an automobile wheel 20 and securely mounted on the inwardly projecting portion of said hub 19 .is a gearwheel 21 whose teeth operatively engage with the teeth of the pinion 17, as more clearly shown in Figs. 3 and i.

The inner side of each of the wheel hubsY 19 is provided with a concentrically disposed integral liange 22 whose outer cylindrical surface is surrounded with a brake band 28, of well known form, which is provided with a frictional lining 24, in the usual manner, and within said flange 22 is a brake ring 25, also of well known form, which is secured to the adjacent disk 12 in a well known manner; both the external brake band 23 and the internal brake ring 25 being adapted to be actuated independently by levers 26 and 27, respectively, in response to endwise movements of brakerods 28 and 29 respectively as indicated in Fig. 2.

The outer end portion ot' each of the hubs 19 is provided with a removable cap 30 which serves to exclude dirt and dust from the roller bearings within the hub 19.

To convert a passenger automobile of a common type, as, tor instance, a Ford automobile, into a motor truck designed to travel at a slower speed, it is only necessary to substitute in place of its rearward running gear and its rearward side springs, the structure illustrated in Figs. 1, 2, 3, and 4 hereinbefore described, by attaching the side rails 5 and 6 of said structure to the rearward portion of the chassis of the automobile whereby said chassis will be lengthened in a rearward direction to serve as a fr nevepoe support iior the floor of :i niotor truck adapted to trirrjv freight; the driving shaft 16 being extended to the engine to he driven thereby.

The rotation of the shaft 1G will coininuniente inotion in 'en obvious innnner to the shafts 15 thereby to rote-.te the pinion 1T which will cause the gezirwheel 21 to ro tute the automobile wheels 2O niueh inore slowljjthnn the shafts 15.

Uhfiouslj', changes nin); he innde in the torina, dimensions and arrangement ot parte of nij' invention without departing' from the spirit thereof.

Tsllnit 1 claim is:

1n :in automobile of the Clues deeoribed, n fixed rear zulle, iin automobile wheel rotatably mounted on erich of the opposite end portions of seid axle, e gear wheel having outer peripheral teeth and mounted eeeurelv on :ind against the inner end of the huh or each ot said wheels, n flanged diel; formed integral with euch ot' the hubs of Vsaid wheels` in n position with its flange encircling the adjacent one of Suid gear wheels, n seperate Vdisk provided with :in inteffrnl cireuiniferentinily grooi'ed huh rigidly mounted on eneli end portion of seid axle in a position adjacent to the inner side of Said gear wheels,n u Seperate Carriage spring; rigidljrv Secured to the huh ot eneh ot Said lust-ninned disks ha: ineens of clamping,` nienihere seated in the grooves of said disk hub, a 'chassis whose reiirwrirdljv extended portion ie connected to hoth ot seid springs, tubular Slint't housings; rigidly connected to and extending hetween Said lest-named disks, two independentljY rotatable shafts disposed end to end in said Sli-'citt housings, earch with its Outer end projected outwnrdljY through the ndjzieent oneioiC said lnet-ntuned disks, n pinion seeureljv mounted on the ontwnrdl)v projeotingl end ot enoh oi" said two shafts in n poei tion to nieeh with the adjacent one otrsnid gear wheels. and inennsrfor Connnunionting rotniwrv inotion to seid two shafts.
